Welcome to the forum duane

Well I know nothing about actuators as my dish is actually driven by a windscreen wiper motor, but if I was faced with your dilemma I would try to determine what type of actuator you have i.e. make model and thus required voltage. Then find a supply to suit. I would have guessed 12V, 24V or 36 V DC but that is a complete guess. Although 12V would actually be easier as a car battery is 12V DC hence easy to check out due to their being a number of cars on the roads these days:eek:. Opening the casing may reveal some details if there is no label on the outside.

As regards a system for £100, I doubt you will find one with a built in positioner for that sum of money.

Inside the actuator there will be a DC motor. Connecting a voltage across the motor terminals should make it move.Swapping the wires round should make it move the other way. There will be other connectors on the actuator for sensing its position, for testing you don't want to connect anything to those as it could fry the unit. The motor connectors/wires should be labelled M1 and M2 or something like that.

If its a 36V motor, connecting 12V across it should still make it move, but very slowly. Don't connect to the wrong terminals though.
